Each week, a picture of a defect observed during a routine home inspection will be presented and reviewed (for info only). The purpose is to educate homeowners, home buyers and real estate agents about important components of a residential property which, if defective, could be a personal safety issue or result in significant costs for repair. In addition, learning proper terminology will assist in the identification, communication, and review of the condition of the elements in a home.
Observation: Gas furnace (medium efficiency) has insufficient clearance of exhaust flue from combustible materials.
Explanation: Combustible materials are noted to be in close proximity to the exhaust flue for the furnace.
Impact / Consequences: To reduce the risk of fire, adequate clearances are required between the exhaust flue and combustible surfaces or materials. Note that manufacturer’s specifications for clearances may vary for various furnaces and installations, and the determination of safe clearances is generally performed by heating technicians. It is suggested that a certified heating specialist be consulted to review the installation for safety.
Summary:
One of the most critical area to look at in a home is the venting of combustible gases. Homes having natural gas, propane, oil or wood burning appliances (furnace, stove, water heater, fireplace etc.) must safely vent the products of combustion properly to the outdoors. Toxic compounds present in combustion gases can lead to problems ranging from nuisance headaches to serious illness, carbon monoxide poisoning and even death. Insufficient clearance of hot exhaust flues from combustible materials (wood, drywall, ceiling tile, roofing) can cause a fire. Flue pipes can be single or double walled, and the clearances depend on the type and efficiency of appliance being vented. Improperly sized or routed flue pipe can result in poor appliance draft conditions. Information is typically found on the labels attached to the pipe and in the manufacturer’s installation instructions. If there are any questions, a certified heating contractor will know the local building codes and should be consulted. Also, carbon monoxide (CO) alarms should be used with gas or oil furnaces and water heaters, and with fireplaces. These devices should be installed close to the combustion appliance being monitored. Having a CO detector close to bedrooms is also a good idea.
